Insulators Ceramics engineers are testing a new formulation for the material used to make insulators for power lines. They will try baking the insulators at four different temperatures, followed by either slow or rapid cooling.
 
  They want to try every combination of the baking and cooling options to see which produces insulators least likely to break during adverse weather conditions.
  a) What are the experimental units?
  b) How many factors are there?
  c) How many treatments are there?
  d) What is the response variable?
